QPL9547

    0.1 - 6 GHz Ultra Low-Noise LNA

    Key Features

    • 0.1 - 6 GHz Operational Bandwidth
    • Ultra low noise figure, 0.3 dB NF @ 1.9 GHz
    • Bias adjustable for linearity optimization
    • Shut-down mode pin with 1.8V logic
    • Maintains OFF state with high PIN drive
    • Unconditionally stable

    The QPL9547 is a high-linearity, ultra-low noise amplifier in a small 2.0 x 2.0 mm surface-mount package. At 1.9 GHz, the amplifier typically provides 19.5 dB gain, +39 dBm OIP3 at a 65 mA bias setting, and 0.3 dB noise figure. The LNA can be biased from a single positive supply ranging from 3.3 to 5 volts. The device is housed in a green/RoHS-compliant industry-standard 2.0 x 2.0 mm package.

    The QPL9547 is bias adjustable and requires minimal external components to operate. It also has a power down control capability integrated into the die for TDD applications.
